Why teams trust this converter
Zero-Trust Ready
Files never leave the tab. WMV binaries live inside WebAssembly memory and are disposed of immediately after producing a MP4 output.
Format-Aware Presets
We tune FFmpeg flags so WMV characteristics (color depth, metadata) persist when writing MP4 deliverables.
Ops-Level Observability
Each run exposes duration, file size deltas, and CPU hints so production teams can benchmark WMV → MP4 workflows.
